Introduction Ultrasound, a technology that utilizes high-frequency sound waves to visualize internal body structures, has become an indispensable tool in modern medicine. From the early beginnings of ultrasound phenomenon exploration in the late 19th century to the initial diagnostic devices in the 1950s, the evolution of ultrasound technology and its application in medicine has continuously advanced. Beyond the basic imaging mechanism that uses sound wave reflection to reconstruct images of internal organs, various types of ultrasound probes have been developed to meet specific diagnostic needs, including conventional probes like linear, convex, and sectoral, as well as specialized probes for unique medical applications. Research goal This research was made with the intention of showing the opinions of nurses in the Republic of Croatia about ultrasound use in nursing and comparing them. With the help of the thesis, we want to show the situations in which ultrasound use would help nurses in their everyday work, how it would improve patient outcomes and what do nurses think about the use of ultrasound. Subjects and methods The respondents were nurses in the Republic of Croatia. A total of 105 responses to the survey questionnaire were received. The survey questionnaire was formulated to examine attitudes with the help of a Likert scale in such a way that from the fourth to the eighth question we added a higher number on the scale to positive attitudes, while from the ninth to eleventh question the reverse was done (a higher number on the scale was added to negative attitudes). Results We had three hypotheses in our research. Hypothesis 1 assumes the nurses have negative attitudes about the use of ultrasound in nursing. Hypothesis 2 hypothesizes that younger nurses have more positive attitudes about the use of ultrasound in nursing than their older colleagues. Hypothesis 3 assumes that highly educated nurses have more positive attitudes toward the use of nursing ultrasound. With this research all hypotheses were rejected. Conclusion At the end of this research, we can say that among nurses in the Republic of Croatia, the desire for further training and education prevails, at least as far as ultrasound is concerned. Other types of education represent a good topic for some future research.
